Main pier construction method for complex embankment area of tidal river channel
The invention discloses a main pier construction method for a complex embankment area of a tidal river channel. The main pier construction method comprises the steps that firstly, the construction position of a composite cofferdam is planned and determined; step 2, constructing a trestle; thirdly, a cast-in-situ bored pile supporting system is constructed; fourthly, a locking steel pipe pile cofferdam system is constructed; 5, constructing a main pier bearing platform and a stand column; and sixthly, the quay wall is rebuilt. Therefore, before construction of the fore shaft steel pipe pile cofferdam system, a pipe gallery-shaped cast-in-situ bored pile supporting system is arranged between the cofferdam construction position of the fore shaft steel pipe pile cofferdam system and the flood control wall so as to effectively support and block soil around the flood control wall; and soil around the flood control wall is prevented from collapsing towards the cofferdam construction position in the excavation process of the fore shaft steel pipe pile cofferdam system, and the construction safety is ensured.
本发明公开了一种潮汐河道复杂堤岸区域的主墩施工方法，包括：步骤一、规划确定复合围堰施工位置；步骤二、栈桥施工；步骤三、钻孔灌注桩支护体系施工；步骤四、锁口钢管桩围堰体系施工；步骤五、主墩承台及立柱施工；步骤六、重新建设岸墙。由此可见，本发明在锁口钢管桩围堰体系施工前，先在锁口钢管桩围堰体系的围堰施工位置与防汛墙之间设置一道管廊状钻孔灌注桩支护体系，以有效地对防汛墙周围的土体进行支挡，防止锁口钢管桩围堰体系开挖过程中造成防汛墙周围的土体朝向围堰施工位置坍塌，确保施工的安全性。
